You can also try licorice root. Organic Licorice root has a deep, enduring sweetness and is prized for its ability to ease coughs and colds, soothe sore throats and increase circulation. Licorice root is consumed as a natural medicine in Arabia, Africa, India, Asia and Europe. It is also the base of many Chinese, Ayurvedic and Korean herbal healing formulas. It goes great with ginger as a tea.
Black Elderberry is also worked really well for us.
